 and weep this circle concentric with the Equinoctial, and this is the parallel of Cancer, which will be 66° 32' from the Pole, or 33° 16' on the Sector. Then, to find the Tropic of Capricorn, you must make 45° on thee lower Tangents a parallel distance of 45° on the upper Tangents, and take 23° 28' beyond that, for the parallel of Capricorn. Then, the Arctic Circle is 23° 30' from the Pole: and thee are all the concentric Circles in the Plane, except the Circle of the Months, which is near the outward edge of the Planisphere. The next Circle is the Ecliptic, the apparent annual path of the Sun, and it is drawn thus:— et off the Secant of 23° 30' from Cancer, on the Soltitial Colure towards the Pole, and this hall be it’s center; and it’s Pole is at the interection of the Arctic Circle, and the Meridian or Soltitial Colure; in this Circle, the igns of the Zodiac are placed; and, in tables of the Right Acenion of the Ecliptic, you will find the proper diviions of this Circle into igns and degrees; then lay a thread, or an Index, from the Pole, through every degree of Right Acenion of the Ecliptic, and it will give points in this Circle where all the Signs and Degrees do fall; the fixed Stars are laid down the ame way by their right Acenion and Declination as found in the tables of the Stars, and thoe in my Planisphere are all of the firt and econd Magnitude, and their places computed up to the preent year 1802, incluive.— Then through the firt points of Cancer and Capricorn, draw a traight line, and this will be the Meridian and Soltitial Colure; then again through the firt points of Aries and Libra draw another line,
